Linus Torvalds a1228f048a Power management fixes for 6.17-rc6
- Restore a pm_restrict_gfp_mask() call in hibernation_snapshot() that
    was removed incorrectly during the 6.16 development cycle (Rafael
    Wysocki)
 
  - Introduce a function for registering a perf domain without triggering
    a system-wide CPU capacity update and make the intel_pstate driver
    use it to avoid reocurring unsuccessful attempts to update capacities
    of all CPUs in the system (Rafael Wysocki)
 
  - Fix setting of CPPC.min_perf in the active mode with performance
    governor in the amd-pstate driver to restore its expected behavior
    changed recently (Gautham Shenoy)
 
  - Avoid mistakenly setting EPP to 0 in the amd-pstate driver after
    system resume as a result of recent code changes (Mario Limonciello)

Pull power management fixes from Rafael Wysocki:
 "These fix a nasty hibernation regression introduced during the 6.16
  cycle, an issue related to energy model management occurring on Intel
  hybrid systems where some CPUs are offline to start with, and two
  regressions in the amd-pstate driver:

   - Restore a pm_restrict_gfp_mask() call in hibernation_snapshot()
     that was removed incorrectly during the 6.16 development cycle
     (Rafael Wysocki)

   - Introduce a function for registering a perf domain without
     triggering a system-wide CPU capacity update and make the
     intel_pstate driver use it to avoid reocurring unsuccessful
     attempts to update capacities of all CPUs in the system (Rafael
     Wysocki)

   - Fix setting of CPPC.min_perf in the active mode with performance
     governor in the amd-pstate driver to restore its expected behavior
     changed recently (Gautham Shenoy)

   - Avoid mistakenly setting EPP to 0 in the amd-pstate driver after
     system resume as a result of recent code changes (Mario
